Urgent! Missing Person! Please Help Translate!!

Someone please help me translate this...I am trying to find my father that turned up missing 2 weeks ago today from Tijuana, Mexico. This is a letter from his roommate trying to tell me what happened, and I don't understand! The Names I know in it are Doug (my dad), Ivan, Paul, Armando, and Ruben. If you can tell me what this says it would be great. Thanks in advance for helping!

Definitely go to the police with this one...especially since this person is asking you to loan him money at the end, possibly to compensate for your father's rent. Someone with the police or court would need to translate this to be filed with the report. Good luck!

Apparently this person that is writting does not know about your father and he is telling you that he (your father) left allegedly to see Paul but it is strange that Armando says he doesn't know anything but took your father's clothes. So this person thinks Armando does know where your father is or he is with your father.
He said he called Paul and Paul said he did not know about your father.
Your father received some money from Paul and some donation too. Apparently he had to pay something back to Paul and he didn't.
he tried to followed Armando but he realized he was being followed. He is advising to "investigate" Armando.
Hope this helps. this is the core.

also willing to help by phone

Hola, and I'm sorry to hear about your situation. If it's easier for you I'd be glad to help by phone as well - just send me an email at Lamariposa47@yahoo.com, and I can respond with my phone #. This letter has a lot of grammar & spelling errors (quite common) and some slang too, so please be sure that whoever helps you - online or in real life - is truly able to understand the letter.
